The content of the invention
Problems to be solved by the invention
However, in roller washing machine, generally before the feedwater of washing process is carried out, the load capacity of the washings in detection roller, and confluent and detergent amount are set according to load capacity.Load capacity is for example according to so that the rotary speed that washings is attached to the inner peripheral surface of roller makes the roller put on the rotary load of roller when being rotated to detect.
Because washings is in the state of drying, coefficient of friction becomes bigger than the state of soaking, thus easily produces cloth damage.Because detection load capacity is carried out before being fed water into water jacket, thus when detecting load capacity, usual washings is dry.Therefore, it is possible to produce the cloth damage of washings when rotating roller.
Particularly, it is provided with the rear portion of roller in the roller washing machine of rotary body, it is also possible to the cloth damage of washings can be produced due to rotary body rotation when detecting load capacity.
The present invention be in view of the problem and complete, its object is to the cloth damage of washings there is provided a kind of roller washing machine, can be prevented when detecting load capacity.
The solution used to solve the problem
The roller washing machine of the major way of the present invention, possesses：Water jacket, is configured in housing；Roller, is configured in the water jacket, and can be pivoted about with trunnion axis or relative to the inclined sloping shaft of horizontal direction；Rotary body, configuration has the protruding part being in contact with washings on surface at the rear portion of the roller；Drive division, it can be operated with the first driving form and the second driving form, wherein, first driving form is the driving form for making the roller and the rotary body be rotated with mutually different rotary speed, and the second driving form is the driving form for making the roller and the rotary body be rotated integrally with identical rotary speed；And control unit.Herein, the control unit detects the load capacity of the washings in the roller, and the drive division is operated with the described second driving form when detecting the load capacity.
According to above-mentioned structure, during detection load capacity, because roller and rotary body are rotated integrally, rotary body does not rotate relative to roller, thus does not have the situation for the rotary body friction that washings is rotated.Accordingly, it is capable to without worrying because rotary body rotates and causes the cloth of washings to carry out load capacity detection with damaging.
In the roller washing machine of the manner, the control unit is configured to, the drive division is set to be operated with the described second driving form, to be rotated the first rotary speed of inner peripheral surface that the roller can at least be attached to the roller with washings, based on the rotary load that the roller is applied to when making the roller be rotated with first rotary speed, to detect the load capacity.
More specifically, the drive division can use the structure for the motor for including the roller and producing the torque for making the rotary body rotation.There is provided the motor driving part of driving current in addition, roller washing machine can also possess to the motor and detect the current detecting part of the driving current.And, the control unit makes the motor be operated with the described second driving form, to make the roller be rotated with first rotary speed, and based on the size of the driving current that the roller detected when being rotated with first rotary speed by the current detecting part is made, detect the load capacity.
In order to detect load capacity, in the case of the structure for using the rotary speed of inner peripheral surface that roller can be attached to roller with washings to be rotated, during the structure for making drive division be operated with the first driving form when using detection load capacity, because faster rotary speed is rotated when rotary body is with than washing process, rinse cycle, thus more likely produce the cloth damage of washings.Therefore, in such a configuration, using detection load capacity When make drive division with the second structure for being operated of driving form because need not more worry the cloth damage of washings, more preferably this structure.
As described above, in order to detect load capacity, in the case of using the structure that the rotary speed for the inner peripheral surface for enabling roller to be attached to roller with washings is rotated, can further use following structures：The control unit in order to detect the load capacity and before the drive division is operated with the described second driving form, the drive division is set to be operated with the described first driving form, so that the second rotary speed for enabling the roller to be rolled with washings in the roller is rotated.
Using such structure, before detection load capacity, by making the washings in roller roll, washings can be loosened.Thus, it due to the inner peripheral surface that washings makes it be attached to roller can be loosened when detecting load capacity, thus can suppress to cause roller eccentric rotary because the concentration of washings is attached, load capacity is detected well so as to precision.Also, because washings not only rolls because of the rotation of roller, it can also be stirred by rotary body, thus roll into a ball into the washings of one and become easier to be loosened.
In the case of using above-mentioned structure, the structure for the braking parts for being also equipped with being braked for the roller to rotation can be used.In this case, the control unit is braked when making the roller stopping of rotation with second rotary speed by the braking parts to the roller.
If using such structure, roller rapidly stops due to being braked, thus now applies very big inertia force to the washings in roller, so that the washings for rolling into a ball into one becomes easily to be loosened.

Clutch drive apparatus 750 includes actuator 751 and action bars 752.Actuator 751 makes action bars 752 move forwards, backwards.The bottom of action bars 752 and clutch lever 730 links.The bottom of clutch lever 730 can be rotated relative to action bars 752.
Bar support 740 and clutch drive apparatus 750 are fixed on installing plate (not shown), and the installing plate is installed on bearing unit 400 or water jacket 20.
It should be noted that clutch lever 730, bar support 740 and clutch drive apparatus 750 constitute the portion of travel mechanism for moving clutch body 720.
Drive division 30 driving form from single shaft driving form be switched to Two axle drive form in the case of, As shown in Fig. 2 action bars 752 is released forwards from the inside of actuator 751.The bottom of clutch lever 730 is promoted by action bars 752 and moved forwards, and clutch lever 730 is rearward rotated centered on fulcrum 741.The upper end of clutch lever 730 is rearward moved, and clutch body 720 is promoted by the upper end of clutch lever 730 and rearward moved.Thus, the rear rack 725 of clutch section 721 and the rack 515 of wing belt wheel 510 engage.
When rear rack 725 and rack 515 engage, because clutch section 721 and wing belt wheel 510 are fixed in a rotational direction, so as the rotation of wing belt wheel 510 can be passed to the state of the second rotary shaft 300 via clutch section 721 and clutch guider 710.In such a state, when motor 100 is rotated, the rotation passes to the second rotary shaft 300 via wing reducing gear 500, and the rotary body 24 for being fixed on the second rotary shaft 300 is rotated.Rotary body 24 is rotated with the rotary speed of motor 100 according to the rotary speed after being reduced by the speed reducing ratio that wing reducing gear 500 is produced.In addition, the rotation of motor 100 passes to the first rotary shaft 200 via Cold Oil Electronic Cylinder 600, the roller 22 for being fixed on the first rotary shaft 200 is rotated.Roller 22 is rotated with the rotary speed of motor 100 according to the rotary speed after being reduced by the speed reducing ratio that Cold Oil Electronic Cylinder 600 is produced.As noted previously, as the speed reducing ratio that Cold Oil Electronic Cylinder 600 is produced is flown wing to wing, the speed reducing ratio of the generation of reducing gear 500 is bigger, so rotary body 24 is with the rotary speed faster than roller 22, with the rotating Vortex of roller 22.
Herein, clutch section 721 is together rotated with wing belt wheel 510, but be due to clutch lever 730 links with linking the enclosure 722 of clutch section 721 with the state rotated freely, even if thus clutch section 721 rotated, the rotation also hardly passes to clutch lever 730.
On the other hand, drive division 30 driving form from Two axle drive form be switched to single shaft driving form in the case of, as shown in figure 3, action bars 752 be retracted actuator 751 inside.I.e. action bars 752 is rearward moved.The bottom of clutch lever 730 is pulled by action bars 752 and rearward moved, and clutch lever 730 is rotated forwards centered on fulcrum 741.The upper end of clutch lever 730 is moved forwards, and clutch body 720 is promoted by the upper end of clutch lever 730 and moved forwards.Thus, the preceding rack 724 of clutch section 721 and the rack 615 of roller belt wheel 610 engage.
When front gear rack 724 and the engaging of rack 615, because clutch section 721 and roller belt wheel 610 are fixed in a rotational direction, thus as the rotation of roller belt wheel 610 can be passed to the state of the second rotary shaft 300 via clutch section 721 and clutch guider 710.In such a state, when motor 100 is rotated, the rotation passes to the first rotary shaft 200 and the second rotary shaft 300 via Cold Oil Electronic Cylinder 600, so that roller 22 and rotary body 24 are rotated.Roller 22 and rotary body 24 are with motor 100 rotary speed is rotated integrally in the same direction according to the rotary speed after being reduced by the speed reducing ratio that Cold Oil Electronic Cylinder 600 is produced.
It should be noted that in single shaft driving form, when motor 100 is rotated, wing belt wheel 510 is also rotated along with the rotation.But, wing belt wheel 510 is dallied only in relation to the second rotary shaft 300, and the rotation of wing belt wheel 510 is not transferred to the second rotary shaft 300.

And then, storage part 802 includes load scale 802a, feedwater scale 802b and detergent scale 802c.Fig. 8 (a), (b) and (c) is to represent load scale 802a, the figure for the scale 802b and detergent scale 802c that feeds water respectively.
As shown in Fig. 8 (a), in load scale 802a, the scope of the difference of multiple load capacity that are stored with and second current value corresponding with each load capacity and the first current value.First current value is supplied to the value of the driving current of motor 100 when being and roller 22 is rotated with the first attaching speed.First attaching speed is that the centrifugal force force of gravity for the washings being applied in roller 22 is big, and can make washings be attached to roller 22 inner peripheral surface rotary speed.Second current value is supplied to the value of the driving current of motor 100 when being and roller 22 is rotated with the second attaching speed faster than the first attaching speed.In addition, the first attaching speed and the second attaching speed are equivalent to the first rotary speed of the invention.
In the case where making roller 22 be rotated with the first attaching speed or the second attaching speed, because load capacity is more, the bigger rotary load so as to be applied to motor 100 of rotary load for being applied to roller 22 is bigger, thus the first current value and the second current value are bigger.Load capacity merely add it is a certain amount of in the case of, the incrementss of the second current value are more than the incrementss of the first current value.Therefore, the difference of more second current values of load capacity and the first current value is bigger.In load scale 802a, difference is bigger, then the value of corresponding load capacity is bigger.The load capacity corresponding with the scope of each difference is determined beforehand through test etc..
As shown in Fig. 8 (b), in feedwater scale 802b, multiple load capacity that are stored with and the confluent corresponding with each load capacity.Because load capacity is more, washing is accomplished by more waters, therefore in feedwater scale 802b, the value of load capacity is bigger, then the value of corresponding confluent is bigger.
As shown in Fig. 8 (c), in detergent scale 802c, multiple load capacity that are stored with and the detergent amount corresponding with each load capacity.Because load capacity is more, washing is accomplished by more detergent, therefore in detergent scale 802c, the value of load capacity is bigger, then the value of corresponding detergent amount is bigger.
Control unit 801 is based on from operating portion 803, level sensor 804 and current detecting part 805 etc. Each signal, according to the program for being stored in storage part 802, display part 806, motor driving part 807, feedwater drive division 808, draining drive division 809, clutch drive division 810 and door lock assembly 811 etc. are controlled.
Roller washing machine 1 carries out user and operated by the washing of the mode selecting button 803c washing modes selected.In washing operating, washing process, middle dehydration, rinse cycle and final dewatering process are performed in order.In addition, according to washing mode, can sometimes carry out dehydration and rinse cycle in the middle of more than twice.
In washing process and rinse cycle, the driving form of drive division 30 is switched to Two axle drive form.In the predetermined water level of the internal memory ponding of water jacket 20 to the lower edge for not arriving input port 11 so that the washings in roller 22 is dipped into water, in this condition, motor 100 is alternately rotated and reverse.Thus, roller 22 and rotary body 24 are alternately rotated and reverse in the state of the rotary speed of rotary body 24 is faster than the rotary speed of roller 22.Now, roller 22 becomes the small rotary speed of force of gravity to act on the centrifugal force of washings and rotated.
Washings in roller 22 is lifted by lifting rib 23 to be fallen, and is rolled in roller 22.Thus, washings is foundered the inner peripheral surface of roller 22.In addition, at the rear portion of roller 22, the protruding part 24a of rotary body 24 of the washings with rotating is in contact, and washings is rubbed by protruding part 24a, stirred.Thus, washings is cleaned or rinses.
So, when being washed and being rinsed, due to except the mechanical force produced by the rotation of roller 22, also assigning the mechanical force produced by rotary body 24 to washings, thus the raising of cleaning performance can be expected.During middle dehydration and final dewatering, the driving form of drive division 30 is switched to single shaft driving form.Motor 100, i.e. roller 22 and rotary body 24 are so that the rotary speed that the centrifugal force of the washings acted in roller 22 is far longer than gravity is rotated integrally.Washings is by the effect of centrifugal force, and the inner peripheral surface for being pressed against roller 22 is dehydrated.
So, in dehydration, because roller 22 and rotary body 24 are rotated integrally, therefore, it is possible to be not rotated in the washings for making to be attached on roller 22 in the case that body 24 stirs, washings is dehydrated well.
In addition, in the roller washing machine 1 of present embodiment, when washing operation start, before washing process is carried out, first, detect the load capacity of the washings in roller 22, and confluent and detergent amount determined based on the load capacity detected, it is determined that confluent and detergent amount shown respectively by confluent display part 806c and detergent amount display part 806d.
Fig. 9 is the flow chart of the control process for the confluent and detergent amount for representing that display is corresponding with load capacity.Figure 10 (a) is represents the flow chart of loose handling, and Figure 10 (b) is the flow for representing load detection process Figure.
When washing operation start, start Fig. 9 control process.Starting the initial of washing operating, the driving form of drive division 30 is switched to single shaft driving form.
Reference picture 9, control unit 801 makes actuator 751 work and causes the movement of the side of 720 guide vane belt wheel of clutch body 510 first, and the driving form of drive division 30 is switched into Two axle drive form (S11) from single shaft driving form.
When washings is put into roller 22, user sometimes can be piecemeal put into washings in roller 22, and sometimes multiple washings can be rolled into a ball into one puts into roller 22.In the case where washings is rolled into a ball into an input, keep the state constant, when in order to detect load capacity, accelerating when being rotated up rotary speed and reaching that washings is attached to the rotary speed of the inner peripheral surface of roller 22 of roller 22, washings easily concentrates a certain position for the inner peripheral surface for being attached to roller 22.
Therefore, control unit 801 carries out the loose handling (S12) shown in Figure 10 (a) before detection load capacity is carried out.
Reference picture 10 (a), control unit 801 makes the right rotation of motor 100 (S101), to make roller 22 carry out right rotation with tumbling rate.Tumbling rate is the rotary speed for enabling the centrifugal force force of gravity for acting on washings small and making washings be rolled in roller 22.For example, in the case where the internal diameter of roller 22 is 520mm or so, tumbling rate is set as 45rpm.Second rotary speed of the tumbling rate equivalent to the present invention.
(S102 when by the defined working time：YES), control unit 801 stops being powered to motor 100, roller 22 is temporarily ceased (S103).Then at once, control unit 801 makes the anticlockwise of motor 100 (S104), to make roller 22 carry out anticlockwise with tumbling rate.
(S105 when by the defined working time：YES), control unit 801 stops being powered to motor 100, roller 22 is stopped (S106).Then, control unit 801 judges whether roller 22 has carried out the left rotation and right rotation (S107) of stipulated number.(the S107 if the number of times of left rotation and right rotation is not reaching to stipulated number：NO), processing is back to step S101 by control unit 801, makes the alternately right rotation and anticlockwise (S101~S106) again of roller 22.So, right rotation and anticlockwise is repeated in roller 22, and the rolling and left-handed rolling of dextrorotation is repeated in washings, untill the left rotation and right rotation of roller 22 has carried out defined number of times.Thus, exist in roller 22 in the case of rolling into a ball into the washings of one, the washings for rolling into a ball into one is loosened.And then, now, the driving form of drive division 30 has been switched to Two axle drive form, and at the rear portion of roller 22, rotary body 24 is rotated relative to roller 22.Therefore, washings is also stirred by rotary body 24, and the washings for rolling into a ball into one becomes easier to be loosened.
(the S107 when the number of times of left rotation and right rotation reaches stipulated number：YES), control unit 801 terminates ravelled spot Reason.
Fig. 9 is returned to, at the end of loose handling, control unit 801 makes actuator 751 work and clutch body 720 is moved to the side of roller belt wheel 610, make the driving form of drive division 30 switch to single shaft to drive form (S13) from Two axle drive form.Then, control unit 801 carries out the load detection process (S14) shown in Figure 10 (b).
Reference picture 10 (b), control unit 801 makes the single direction rotation of motor 100 (S201) so that roller 22 carries out single direction rotation with the first attaching speed.First attaching speed is the rotary speed for the inner peripheral surface for enabling the centrifugal force force of gravity for acting on washings big and making washings be attached to roller 22.For example, in the case where the internal diameter of roller 22 is 520mm or so, the first attaching speed is set as 65rpm.Because by loose handling just now, the washings in roller 22 is loosened, thus when roller 22 is when spinning up to the first attaching speed, washings easily disperses and is attached on the whole inner peripheral surface of roller 22.
Then, control unit 801 detects the value for the driving current for being supplied to motor 100 by current detecting part 805 when roller 22 is rotated with the first attaching speed, and is stored in storage part 802 (S202) as the first current value.
Control unit 801 accelerates the rotary speed of motor 100, motor 100 is rotated (S203), to make roller 22 with the second attaching speed single direction rotation more faster than the first attaching speed.For example, in the case where the internal diameter of roller 22 is 520mm or so, the second attaching speed is set as 165rpm.Then, control unit 801 detects the value for the driving current for being supplied to motor 100 by current detecting part 805 when roller 22 is rotated with the second attaching speed, and is stored in storage part 802 (S204) as the second current value.
Control unit 801 obtains the difference of the second current value and the first current value that are stored in storage part 802, and with reference to load scale 802a, load capacity (S205) is determined by the difference obtained.Then, control unit 801 is stopping being powered to motor 100, makes after the stopping of roller 22 (S206), to terminate load detection process.
Herein, when carrying out detection load capacity, the driving form of drive division 30 has switched to single shaft to drive form, and roller 22 and rotary body 24 are rotated integrally.That is, rotary body 24 does not rotate relative to roller 22.
When assuming that motor 100 rotates under Two axle drive form, because rotary body 24 is rotated relative to roller 22, thus at the rear portion of roller 22, the rotary body 24 that there is a part of washings with rotating is in contact, the possibility rubbed by rotary body 24.The rotary speed that roller 22 is attached to the inner peripheral surface of roller 22 with washings is rotated because the rotary speed than washing process, rinse cycle, loose handling before rotary speed faster, therefore, the rotary speed of rotary body 24 also accelerates.Accordingly, there exist the possibility that cloth damage occurs for the washings contacted with rotary body 24.
In the present embodiment, because roller 22 and rotary body 24 are rotated integrally, rotary body 24 is relative to rolling Cylinder 22 does not rotate, therefore washings will not be rubbed by the fast rotary body 24 of rotary speed, will not produce because of the cloth damage of washings caused by rotary body 24.
In addition it is also possible to the difference based on two driving current values under different rotary speeies unlike present embodiment, but load capacity is determined based on a driving current value.However, there is the possibility created a difference by the variation in voltage of outside source power supply, the foozle of product in driving current value.When obtaining the difference of two driving current values as present embodiment, because such difference can be offset, the precision of detection load capacity can be improved.
Fig. 9 is again returned to, control unit 801 is respectively referred to the scale 802b and detergent scale 802c that feeds water, determined confluent and detergent amount (S15) based on the load capacity after determination.Then, control unit 801 includes the confluent after determination on confluent display part 806c, and the detergent amount after determination is included on detergent amount display part 806d (S16).Then, control unit 801 terminates Fig. 9 control process.
User puts into detergent box 50 to being confirmed by the detergent amount display part 806d detergent amounts shown, and by the detergent of the amount.And then, control unit 801 is in washing process and rinse cycle, the feedwater for the confluent being only determined into water jacket 20.
<The effect of embodiment>
According to present embodiment, in the load capacity for detecting the washings in roller 22, drive division 30 is operated with single shaft driving form.Under single shaft driving form, because roller 22 and rotary body 24 are rotated integrally, rotary body 24 does not rotate relative to roller 22, thus the rotary body 24 that washings will not be rotated rubs.Accordingly, it is capable to which the cloth damage for being not concerned about the washings caused by rotary body 24 carries out detection load capacity.
And then, according to present embodiment, roller washing machine enables the rotary speed for the inner peripheral surface that roller 22 is attached to roller 22 with washings to be rotated, and is applied to the rotary load of roller 22 to detect load capacity during based on the rotation.More specifically, in the present embodiment, the difference of the driving current value of the motor 100 detected under driving current value and the first attaching speed based on the motor 100 detected under the second attaching speed detects load capacity.
So, in the case of the structure for using the rotary speed for the inner peripheral surface for enabling roller 22 to be attached to roller 22 with washings to detect load capacity to be rotated, when making the structure that drive division 30 is operated with Two axle drive form when using and detecting load capacity, because rotary body 24 than carrying out faster rotary speed when washing process, rinse cycle to be rotated, thus more likely produce the cloth damage of washings.Therefore, in such a configuration, when making the structure that drive division 30 drives form to be operated with single shaft when being used as present embodiment and detecting load capacity, because needing not worry about the cloth damage of washings, the more preferably structure.
And then, according to present embodiment, before detection load capacity, drive division 30 is operated with Two axle drive form, and to enable roller 22, with washings, the tumbling rate of rolling in roller 22 is rotated.Accordingly, because washings can be loosened before detection load capacity, so can be by the scattered inner peripheral surface for being attached to roller 22 of washings when detecting load capacity.Accordingly, it is capable to suppress the eccentric rotary of roller 22 caused by being attached because of the concentration of washings, load capacity is detected well so as to precision.Also, because washings is not only rolled by the rotation of roller 22, also it is stirred by rotary body 24, thus rolls into a ball into the washings of one and become easier to be loosened.
<Modification>
Figure 11 is the flow chart for representing the loose handling involved by this modification.
In Figure 11 loose handling, compared with Figure 10 (a) loose handling, step S111 processing is added after step S103 processing, step S112 processing has been added after step S106 processing.
In this modification, motor driving part 807, so that acting on the motor 100 of rotation as the short-circuit brake of one of electromagnetic brake, is braked by making the coil short of motor 100 to motor 100.By braking motor 100, so that the roller 22 linked via the rotary shaft 200 of Cold Oil Electronic Cylinder 600 and first with motor 100 is braked.The motor driving part that motor driving part 807 serves not only as the present invention plays a role, and is also played a role as braking parts.
As shown in figure 11, control unit 801 is when making to stop with the roller 22 that tumbling rate carries out right rotation, and stopping is powered (S103) to motor 100, and electromagnetic brake is worked (S111) by motor driving part 807.Similarly, control unit 801 is when making to stop with the roller 22 that tumbling rate carries out right rotation, and stopping is powered (S106) to motor 100, and electromagnetic brake is worked (S112) by motor driving part 807.Therefore, because roller 22 is braked and rapidly stopped, thus now the washings into roller 22 acts on big inertia force, and diplomatic corps is easily loosened into the washings of one.
